Long Distance Detection
Up to 20 meters of operating range

Operating Range is selected by a simple wiring configuration.

Two range settings: long distance (5 to 20 m) and short distance (0.3 to 7 m).Switching of operating range can be easily set with a single input line (operating range select input).This saves the work time for switching.

Cable installation can be as long as 100m.

It covers a wider range of applications with its easy wiring design.
